| Summary: | The University of Washington PBL model is a nonlinear similarity model (with organized large eddies in an equilibrium mean flow) suitable for km-scale to General Circulation Model or Climate numerical models. The theory and verification for this solution are now well established. Researchers who work with winds in the boundary layer with scales from point to 20-km regimes must be aware of this horizontal inhomogenuity in the PBL flow to avoid significant errors. Since the OLE contribute advectively to the mean flow there can be 10-20% (or more) increase in surface winds and fluxes over K-theory models. The model is described and several applications have been made |
